MSP430G2755IDA38R Key Features

• 16?bit core: provides efficient instruction density and predictable execution for control algorithms.
• Integrated 10?bit ADC: enables direct measurement of analog signals with no external converter, reducing BOM and board area.
• Low operating voltage: supports 1.8?C3.6 V systems for longer battery life and simpler power supplies.
• Compact 38?pin package: delivers more I/O and peripherals than smaller packages while remaining suitable for space?constrained PCBs.

Typical Applications

• Battery?powered sensor nodes that require long standby life plus periodic 10?bit analog sampling and low active current draw for extended deployments.
• Industrial control panels that need deterministic timer control, multiple GPIOs and the 16?bit arithmetic for simple control loops or signal conditioning.
• Portable measurement instruments combining low?voltage logic, on?chip ADC channels and modest flash for firmware and calibration data storage.
• Serial?interface devices where UART/SPI/I2C peripherals are used to connect to radios, sensors or power?management components on compact PCBs.

MSP430G2755IDA38R Advantages vs Typical Alternatives

The device offers a clear balance of low power and integration compared with many 8?bit MCUs. Its 16?bit core delivers more efficient arithmetic and smaller code size for math?heavy tasks.
